Incoloy Alloy 800
Introduction
Overview of Incoloy Alloy 800
Nickel alloy 800 is a nickel-iron-chromium super alloy with good strength and excellent resistance to oxidation and carburization in high temperature atmospheres.
It also displays excellent resistance to stress-corrosion cracking and has good creep-rupture strength.
The alloy is often used in heat treating equipment, radiant tubes, thermowells, retorts, muffles, lead pots, heat exchangers, still tubing and other high temperature applications.
Features of Incoloy Alloy 800
- High temperature strength.
- High creep rupture strength.
- Resistant to oxidation and carburization in high temperature environments.
- Good corrosion resistance in many acidic environments.
- Good resistance to many sulfur-containing atmospheres.
Incoloy Alloy 800 Applications
- Heat exchanger tubing for petrochemical processing.
- Valves and other piping components for sulfuric acid plants.
- Equipment for handling hydrogen chloride, acetic acid and sodium hydroxide.
- Flue gas desulfurization systems (scrubbers).
